James T. Mann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sulfonate containing copolymers as mist suppressants insoluble oil (water-based) metal working fluids
    Patent number: 6100225
    Abstract: Aqueous metal working fluids containing a mist suppressing copolymer are disclosed. The copolymer includes hydrophobic and hydrophilic monomers. Optionally, the metal working fluid may be an oil-in-water emulsion.
    Type: Grant
    Filed: July 21, 1997
    Date of Patent: August 8, 2000
    Assignee: The Lubrizol Corporation
    Inventors: Sanjay Kalhan, James T. Mann, Richard A. Denis
  • Multicomponent stabilized hydraulic fluid
    Patent number: 4210542
    Abstract: Mineral oil or synthetic hydrocarbon base hydraulic fluids containing a zinc bis(dialkyldithiophosphate) as an antiwear agent are stabilized against degradation at elevated operating temperatures by the incorporation in the hydraulic fluid of an appropriate Group I or Group II metal phosphonate and a fatty acid imidazoline. For example, a hydraulic fluid containing a zinc bis(dialkyldithiophosphate) is stabilized by the presence of a minor amount of a sodium phosphonate and a tallow fatty acid imidazoline.
    Type: Grant
    Filed: December 1, 1978
    Date of Patent: July 1, 1980
    Assignee: Gulf Research and Development Company
    Inventor: James T. Mann
  • Stabilized hydraulic fluid composition
    Patent number: 4210541
    Abstract: Mineral oil or synthetic hydrocarbon base hydraulic fluids containing a zinc bis(dialkyldithiophosphate) as an antiwear agent are stabilized against degradation at elevated operating temperatures by the incorporation in the hydraulic fluid of an appropriate Group I or Group II metal dialkylnaphthalene sulfonate and a fatty acid imidazoline. For example, a hydraulic fluid containing a zinc bis(dialkyldithiophosphate) is stabilized by the presence of a minor amount of zinc dinonylnaphthalene sulfonate and a tallow fatty acid imidazoline.
